Referring more particularly to the draw 7 i erably in alinement with theshaft 23 but separate therefrom, is another shaft 37 that has of anysuitable material,

Journaled in the casing and in suitable bearings is a threaded shaft 11which has a away from the 1928. Serial No. 292,842.

constant direction of rotation, and loosely mounted upon the'shaft is aclutch member 12. A clutchrmember 13 is keyed to the shaft lland isadapted to be shifted into and out of engagement with the clutch member127 for locking and unlocking the clutch member. 12 with respectto theshaft.

1 Connected with the clutchmember' 12 and for rotation therewith is agear 14 with which a gear 15 meshes. Connected with the:

gear 15 for rotation therewithis a gear 16,

,l the'l'atter being secured to a shaft 17 and which shaft is journaledin suitable bearings 18.

A pinion gear 19 is connected with the shaft to a shaft 21, the gear 20meshing with a gear 22 that'is secured to a shaft 23 for rotationtherewi'tln This shaft 23 is mounted'in suit-' this shaft receives itsmotion from any'suitable source of power. 1

A spring is providedbetween the disc 25 and shoulder 31 which tendsnormally to hold the friction driveel'ements 25 and 24 in contact witheach other. Figure 3 is a transverse vertical sectional The speed ofrotation of the shaft 23 and consequently the shaft 11 is controlledby:-

shifting the friction element 24 toward and axis of rotation of thefriction disc 25.

32 which is connected to a shaft 33 that extends through the top 'of thecasing, and to the shaft is conn'ected a handle or button 34 arranged ina suitable positionfor the operator. vided which 'co-operates withgraduations 36 to indicate the rate of speed of the shaft;

'Journaled in suitable bearings and prefconnected with it an elongatedtoothed por- 'tion38, for a purpose to be set forth. This An indicatoror pointer may be pro-i provided a gear wheel 39 which is looselymounted upon the shaft 37.

' A clutch member 40 is connected with the gear 39 for rotationtherewith and a double clutch member 41 is connected with the shaft 37for rotation therewith and for slidabl'e movement lengthwise thereof sothat one portion of the clutch member 41 will engage the clutch member40 to lock the gear 39 for rtation with the shaft 37 and another portionof thedouble clutch member 41 will-engage a clutch member 42 which isconnected with a L to lock'the' latter gear-:43, loosely mounted uponthe shaft 37,

gear for rotation with the shaft.

By alternately locking and unlocking the reciprocating gears 39 and 43with respect to the shaft 37 the direction of rotation of the 9 shaft 37may be controlled'and this is accomplished in the following manner.Meshing with the gear 39 is a pinion gear 44 which is i 22+20, shaft 21and intermeshing gears 7 secured to the shaft 21 of the-gear 20 forrota- :tion therewith so that when the clutch member 40 is locked to theshaft 37 and the shaft 23 is rotating, motion will be imparted from theshaft 23 through the intermeshing gears 4439 to the shaft 37 whenthe'clutch memher 41 is in the position shown in Figure 2.

When the clutch member 41 is shifted so as to release the clutch member40 and lock the clutch member 42 and gear 43 with respect to the shaft37, motion will be imparted to the shaft37 from the shaft 23,intermeshing gears 22-20-19, shaft 17, gear 16 and gear 43 which-issecured to the clutch member 42 for rotation therewith.

Thus it will be seen that by shifting the clutch member 41 the directionof rotation of the shaft 37 and portion thereof will be 7 controlled.

The clutch member 40 is adapted to be automatically controlled in anysuitable manner so that when the shaft 38 has rotated for any -46 to asuitable support, the other end of the desired extent in one directionthe direction of rotation of the shaft 37 will be reversed.

To that end there is provided an arm or lever 45 pivotally mounted byone end as at lever being'connected with the clutch member41.

Slidable in suitable bearings 47 is a bar or rod 48, one end of which isconnected with a lever 49 pivoted intermediate its ends as at 50, theother end of the lever 49 being connected with the clutch member 13which is shiftable longitudinally upon the shaft 11.

A suitable connection 51 .is provided with the member 48 and the arm orlever 45 and a spring 52 anchored .to a fixed support 53 a and connectedas at 54 with the arm or lever 49, is provided which tends normally toshift the member 48 in a direction to move the arm 1 or lever 45 toposition the clutch member 41 as shown in Figure 2.

nvzasea After the shaft 37 has rotated to any desired extent, means areprovided whereby the direction of rotation of the shaft 37 may be 1reversed and to that end there is provided a.

cam member 55 which isconnected with a shaft 56 journaled in suitablebearings. The cam member 55 is preferably formed ona gear 57 whichlatter meshes with a gear 58 carried by a shaft 59 rotatably supportedin suitable bearings 60 andconnected with the member 48 is ananti-friction roller 61 which is so positioned that at a predeterminedtime I tive train of-gears as already described,"

changing the direction of rotation of the shaft when the clutch member40 and the gear 39 are locked to the shaft 37 a comparatively slow speedof rotation will. be given 'to the shaft 37 by reason of the differentratios of the gears 39 and 44, but when the shaft 37 is rotated in theopposite direction, that is when the clutch member 41 looks the gear 43with the shaft37, the shaft 37 will be given a greater rate ofspeed'ofrotation byreason of the proportion or ratio of the gears 16 and 43 withrespect to each other and with respect to the gears 39-4.4. "1

Thus it will be seen that the shaft 37 will rection and a quick degreeof rotation in the be given a slow degree of rotatlonln one d1- oppositedirection, for a purpose to be setforth.

The cam surface 55 and the gear 57 are rotated through the medium of,the gear 58 i on theshaft 59 and a gear 62 which is secured for rotationwith the shaft 59 andgear 58,

and this gear 62 meshes with another gear 63 secured to a shaft 64 forrotation therewith and which shaft is jour'naled in suitable bearings.

'Another gear; 65 is connected with the gear 63 for rotation therewithand this gear 65 meshes with a gear66, the latter being secured to theshaft 23 for rotation therewith so that when the shaft 23 is rotated bythe driving mechanism embodying the frictional drive elements 2524 thegear 66 will .be rotated, which in turn will rotate the gears 65, 63,62, v58 and the gear 57 to operate the cam element 55 v v These lattergears are so proportioned and the cam element or surface 55 is solocated with respect to the gear 57 that it will engage and shift themember .48 only at a predetermined time in the cycle .of operationthereof. Loosely mounted upon the portion 38 of the .shaft37 is a sleeve67 (see particularly Figures 4 and 7) and which sleeve is free to rotateupon and about the portion 38 of the shaft 37, the said portion 38 beingat all times freely rotatable within the sleeve. Connected withthesleeve 67 is an arm 68, to the eX- .treniity of which is'secured athreaded segment 69 and to the segment is connected a handle 70. The arm68 is of such a length that the segment 69 will engage and rest upon thethreaded shaft 11 so that when the shaft '11 is rotated the sleeve 67,arm 68 and segment 69 will be bodily advanced in directions lengthwiseof the shafts 11 and 88. The

. handle 70 passes through a suitable aperture 71 in the top of thecasing 72 so as to be readily accessible to the operator andthe aperture71 is elongated as shown in Figure 1, so as notto interfere with theadvancing and retracting movement of the arm 68 and sleeve 67 rackmember 7 3 is provided which passes through suitable apertures 74: inthe casing and extends transversely of and across the shafts 11 and 38.The sleeve 67 is provided with an apertured, portion 7 5 in which therack 73 rests and is guided so that the teeth of therack will engage thetoothed portion 38 of the shaft 37 whereby when the shaft 37 is rotatedthe rack 73 will be advanced or retracted according to the direction ofrotation ofthe shaft. Ears 76 may be provided adjacent the bifurcatedportion of the sleeve so as to guide the rack., The segment 69 is alsobifurcated as shown more clearly in Figure 5, and loosely mounted uponthe shaft 11 is a sleeve 77 that is adapted to freely slide length-.Wise of the shaft 11. This sleeve is also bifurcated as at? 8 toreceive and guide the rack '73, a portion 79 of the segment 69projecting into the bifurcation (see particularly Figure 5) for holdingthe rack 73 in position. The bifurcation 78 of the sleeve 7? and thebifurcation of the segment 69 are so arranged that the arm 68 may beraised to elevate the segment 69 out of contact with the shaft 11 so asto permit free longitudinal movement of the sleeves 77 and 67 upon theirrespective shafts without disconnecting the rack 73 from the toothedportion 88 of the shaft 37.

Connected with the rack 73 is a pointer or indicator 80 which may be ofany desired configuration adapted to move across the face of a surface81 containing the subject matter 82 that is to be indicated.

By the provision of the toothed portion 38 of the shaft 37 the rack 73and indicator will be given a movement from left to right or in text.When the indicator 80 reaches the end of the line or the limit of itsmovement toward the right, the shaft 11 will be automatically set inoperation in the manner already set forth, that is by the engagement ofthe cam with the member 5L8 to rock the lever 49 and shift the clutchmember 13 to lock the gear 14 with the shaft 11. At the same time theshaft 37 will be locked for rotation through the medium of the same camshifting the member 48 and rocking the arm or lever 45 to shift theclutch member ll and thereby unlock the gear 39 with respect to theshaft 37 and lock the clutch member 42 and gear 43 with respect to theshaft 37. This will cause the pointer or indicator 80 to be given aquick return movement and at the same time and as the shaft 11 is beingrotated, the segment 69, arm 68 and sleeve 67 will be advanced by theshaft 11 so that the pointer or indicator 80 will drop down to the nextline at the extreme left thereof as indicated in dotted lines in Figure2. he same operation will then be repeated, causing the pointer orindicator to successively move from left to right to the full end of oneline and then drop down on its return movement to be properly positionedat the next line and so on.

Should it be desired to re-position the pointer or indicator 80 at anypoint on the text or matter being indicated thereby. it is onlynecessary to grasp the handle and raise the segment 69 and arm 68without interfering with the rack 73 and pointer 80, therebydisconnecting the arm 68 and segment 69 with respect to the shaft 11,which will permit these parts to be freely moved longitudinally of therespective shafts.
